Can HP Data Protector get backup source files from a text file?
If not, how can I get a backup of only changed or created files during the day, like ntbackup's daily backup type (without full backup) with HP Data Protector.
It's not possible to perform an incremental backup without a full backup.
A full backup works as a reference to compare what has changed and what hasn't.
Dataprotector uses a concept called enhanced incremental, and uses it to do a backup schema called incremental forever.
With conventional incremental backup, the criterion for determining whether a file has changed since a previous backup is the file’s modification time, however, there are cases where this criterion is not effective. For example, if a file has been renamed, moved to a new location, or if some of its attributes have changed, its modification time does not change. Consequently, the file is not backed up in an incremental backup. Such files are backed up in the next full backup. With enhanced incremental backup, Data Protector introduced its own mechanism to reliably detect whether a file has been changed and theref ore should be put into the incremental backup.
This mechanism includes any changes that any file has sustained during any given day.
So, no extreme scripting is needed :)
No, Data Protector cannot get a list of files to backup from a
To get a backup of only files altered during the day, you'd need to create a custom backup job linked to a query that selects files based on date modified, and that's a very big headache. It can be done, it's generally more effort than it's worth, and it's probably a much better idea just to a[nother] full back up of the server.
So that you know for next time, the type of backup you're talking about is generally referred to as an incremental or differential backup (depending on vendor and/or country).
